Separating the effect of mechanisms shaping species-abundance distributions at multiple scales in a subtropical forest

Jiajia Cheng, Xiangcheng Mi, Karin Nadrowski, Haibao Ren, Jintun Zhang, Keping Ma
2011 Oikos  
The previous tests of niche and neutral models shaping SADs lead to the claim that SADs are not informative for inferring underlying processes.  ...  These processes are linked with the degree of conspecific aggregation, informing further attempts to refine and parameterize the statistical theory of sampling SADs.  ...  Šizling, Liza Comita, Yongtao Guan, Fangliang He and Guochun Shen for their insightful comments and suggestions on this manuscript.  ...

An Advanced Time-Series InSAR Approach Based on Poisson Curve for Soft Clay Highway Deformation Monitoring

Lingjie Zhu, Xuemin Xing, Yikai Zhu, Wei Peng, Zhihui Yuan, Qing Xia
2021 IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing  
Most of the traditional Interferometric Synthetic Aperture Radar (InSAR) deformation models for highway monitoring are based on a combination of one or several empirical functions, which ignores the underground  ...  The improved InSAR deformation model is based on Poisson Curve, which considers the characteristics of the temporal physical deformation evolution of the soft clay.  ...  The nonlinear deformation component that cannot be fitted by the linear velocity model was contained and modeled in the Poisson curve function, thus was weaker than the Poisson curve-generated results.  ...
